Programmable I/O Tab
The “Programmable IO” tab of MaxSSD is displayed when using SeaI/O devices
featuring programmable inputs or outputs. This tab allows for bank configuration,
input/output configuration, as well as bit-level presets.
Each bank of programmable I/O can be set as either an 8-bit group of inputs or
outputs. By selecting “Bank 1” from the drop-box, clicking the “Bank functions as
Input” radio button, and then clicking the “Set Programmable IO Options” button, the
first 8 PIO bits on the device will now function as inputs. For ease of configuration,
an “All Banks of IO” option is available to configure all of the I/O at one time.
Inputs have no preset mode; therefore, the preset options are disabled for any bank of
inputs. Outputs; however, have bit-addressable presets. These presets are used
whenever the device is powered up or the bank direction changes from input to
output.
NOTE: The output presets, will not lock the outputs into a specified on or
off state. They only set the state of the outputs on a power on or
bank direction change.
